I would say yes, they are more frontloaded. PS3 & 360 each peaked in 2011 which were their 5th & 6th full year on the market, that is incredibly late to peak.
Personally I think Xbox One's peak year will be either 2015 or 2016 & PS4's peak year will be 2016 or 2017.
When the herd loses its way, the shepard must kill the bull that leads them astray.
